Not trying to start anything $hit on this topic, just throwing out a low cost solution to this problem. This is stuff I had in my garage, the most expensive part is the jack which can be had for <$20 at Wally World (although mine is clearly a K-Mart model )
As you can see from the picture, it's just a 2X4 cut to 22 5/8" long, another 2X4 cut a little shorter ( I did the 2nd board for strength and as a spacer to compensate for the jacks shaft travel) a couple of drywall screws to hold them together. An old bottle jack that was floating around my garage from who knows when.
1 - Pull wash plate
2 - Put bolt back in shaft, thread it in about 1/2 way or more
3- Put 2X4 under upper rim of tub
4- Put jack on top of wash plate bolt and crank it up
Disclaimer: this was not my original idea. There is a video on You Tube with a guy using a scissor type jack but he doesn't tell you how long the board needs to be - which is important.
This works great for bearing/shaft replacements, however on units that you just need to pull the basket to retrieve something it can be a PIA getting the basket back on to the crusty shaft so it will float properly. I have resorted to a wire wheel attachment I can put on my impact to clean the shaft up so the basket will float.
